What's your actual cost per 1K successful requests with residential proxies?

We've been running a data pipeline for about 18 months now, and one metric I keep coming back to is the real cost per successful request—not just the price per GB, but the total cost including retries, failed requests, and the engineering time spent debugging.

Here's what I've learned about calculating the true cost:

1. Sticker price is only half the story

Most providers advertise a per-GB rate, but that number doesn't include the requests that fail and get retried. If your provider charges for bandwidth and you're burning bandwidth on failed requests, your effective cost per successful request can be 2–3× higher than the advertised rate.

2. Retries add up faster than you think

We tracked our retry rates across three different providers over six months. The best-performing provider had a 3% retry rate; the worst had 22%. On a pipeline processing 500K requests per day, that's an extra 110K requests—and the bandwidth to go with them. The "cheaper" provider ended up costing us more.

3. Session control matters for cost efficiency

We found that per-request rotation on session-based tasks wasn't just bad for success rates—it was expensive. Burning a new IP for every sub-request in a multi-step workflow meant we were paying 3–4× more IPs than necessary for the same completed session. Switching to sticky sessions cut our IP consumption significantly.

4. Time is money

Every hour spent debugging proxy failures, writing wrapper code, or explaining to stakeholders why the data is late—that's a real cost. A provider with a clean API and reliable infrastructure saves you more in engineering time than any per-GB discount ever could.

We built Pxyedge to address exactly these cost drivers—transparent pay-as-you-go pricing with no hidden bandwidth fees, a clean REST API that takes minutes to integrate, and flexible rotation (per-request or sticky sessions) so you're not paying for IPs you don't need.

Curious—what's your actual cost per 1K successful requests? Have you run the numbers? Would genuinely love to compare notes.
